ISO 15022-1:1999/Cor 1:1999

Overview

ISO 15022-1:1999/Cor 1:1999 is the technical corrigendum to the international standard for securities messaging, specifically focusing on the data field and message design rules and guidelines. Developed by the International Organization for Standardization (ISO) and its Technical Committee ISO/TC 68, this corrigendum addresses important clarifications, particularly concerning the formatting of date fields within securities messages, as defined in the Data Field Dictionary.

This standard, alongside ISO 15022-2, plays a crucial role in enhancing the efficiency, consistency, and interoperability of electronic messaging among financial institutions dealing with securities and related financial instruments.

Key Topics

• Securities Messaging Scheme: Defines a robust framework for the electronic exchange of securities messages through standard data fields and message structures.
• Data Field Dictionary: Provides comprehensive design rules for formulating and utilizing consistent data elements in message formats.
• Technical Corrigendum: Clarifies requirements and offers recommendations on the handling and representation of date fields, especially where the year is denoted in less than four digits.
• Y2K (Year 2000) Readiness: Advises implementers on potential updates or amendments necessary to support four-digit year formatting, aligning with business and regulatory needs for the year 2000 and beyond.
